"acct" Exercise


1. Install acct

	$ sudo apt-get install acct

   Installed tools are :

   lastcomm ac sa

2. Now try them out

	$ last

   	$ sudo lastcomm

	$ ac -p

	$ sudo sa

3. Contemplate output from commands

   See the output and maybe pipe via "head" or "less".
   This is a lot of data. Are there other ways to detect 
   access?
